史前太湖流域,礼器出现在社会初步分化的崧泽文化时期;良渚文化时期已经是一个分层的复杂社会,社会成员分化成为不同的等级、阶层,与此相适应,太湖流域史前社会出现了陶质、石质和玉质三种不同质地的礼器,并有着比较严格的使用制度,太湖流域史前社会的礼仪制度初步形成。 相似文献

In order to interpret strontium and oxygen isotope values in Neolithic human skeletons analysed previously, we begin to map the biologically available strontium, carbon and oxygen isotopic signatures of prehistoric southern Germany by analysing tooth enamel of pigs from archaeological sites distributed around the region. The mapping shows a marked upland–lowland difference in biologically available 87 Sr/ 86 Sr values, ranging between 0.7086 and 0.7103 in the sedimentary lowlands, and from 0.710 to as high as 0.722 in the crystalline uplands of the Odenwald, the Black Forest and the Bavarian Forest. In addition, carbon isotopes in the carbonate fraction of pig enamel were generally about 1–2 more enriched in 13 C in the uplands. Despite the expected depletion of 18 O with altitude, oxygen isotopes in pig enamel showed little correlation with site altitude, although for pig samples not older than the Iron Age there was some geographical correlation withδ18O patterns in modern precipitation. 相似文献

探索和研究表明,岩画断代问题仍然是困扰岩画研究的难题之一,其主要原因是岩画本身不能够提供可供断代的直接依据。本文综述了目前岩画断代研究中经常使用的自然科学和考古学方法及其存在的问题,提出应用AMS14C是今后研究我国岩绘画断代问题的首选方法,解决岩刻画的断代问题则主要有赖于微腐蚀方法。 相似文献

新中国成立初期中南区婚姻制度的改革 总被引:1,自引:0,他引:1
新中国成立前后,中南区由于长期受封建婚姻制度的束缚,各种陋俗在许多地方普遍存在,广大妇女的社会地位极其低下。1950年《中华人民共和国婚姻法》颁布施行后,中南区在全区范围内大张旗鼓地开展了一场宣传和贯彻《婚姻法》的群众运动,经过调查试验、宣传发动和总结表彰,彻底地摧毁了封建婚姻制度,建立起了新民主主义的新型婚姻制度,形成了男女平等、民主和睦的社会新风尚,从而促进了中南区整体性的社会文明与进步。 相似文献

It is now three decades since Waterbolk introduced evaluation criteria to 14C chronology. Despite this, and other subsequent attempts to introduce quality control in the use of 14C data, no systematic procedure has been adopted by the archaeological community. As a result, our databases may be significantly weakened by questionable dates and/or questionable associations between dated samples and the archaeological phenomena they are intended to represent. As the use of chronometric data in general becomes more ambitious, we must pause and assess how reliable these data are. Here, we forward a set of evaluation criteria which take into account archaeological (e.g. associational, stratigraphic) and chronometric (e.g. pre-treatment and measurement) criteria. We intend to use such criteria to evaluate a large 14C dataset we have assembled to investigate Late Glacial settlement in Europe, the Near East and North Africa, supported by the Leverhulme Trust. We suggest that the procedure presented here may at least form the basis of the development of more rigorous, scientific use of 14C dates. 相似文献

This article examines the effect of C.S. Lewis's Irish background on his work. It attempts to contradict the assumption that this Belfast-born writer should be included in the English and not the Irish canon. It emphasises that Lewis saw himself as Irish, was seen by others as Irish, and that his Irish background, contrary to what some have written, was important to him throughout his lifetime. It goes on to demonstrate the ways in which his work was influenced by his youth in Ireland and by the Irish mythology that he loved. Furthermore, this article maintains that, as a child of pre-partition Ireland with roots throughout the island, Lewis was influenced by the country as a whole, not just his native Ulster. Finally, it attempts to understand why Lewis, a proud Irishman, did not do more to promote himself as an Irish writer. 相似文献

The age of Neanderthal remains and associated sediments from El Sidrón cave has been obtained through different dating methods (14CAMS, U/TH, OSL, ESR and AAR) and samples (charcoal debris, bone, tooth dentine, stalagmitic flowstone, carbonate‐rich sediments, sedimentary quartz grains, tooth enamel and land snail shells). Detrital Th contamination rendered Th/U dating analyses of flowstone unreliable. Recent 14C contamination produced spurious age‐values from charcoal samples as well as from inadequately pretreated tooth samples. Most consistent 14C dates are grouped into two series: one between 35 and 40 ka and the other between 48 and 49 ka. Most ESR and AAR samples yielded concordant ages, ranging between 39 and 45 ka; OSL dating results permitted adequate bracketing of the sedimentary layer that contained the human remains. Our results emphasize the value of multi‐dating approaches for the establishment of reliable chronologies of human remains. 相似文献

This paper presents direct evidence of subsistence practices and pottery use at a Late Neolithic site at al-Basatîn, northern Jordan. Measurable concentrations of C16:0 and C18:0 were recovered from 8 of 10 archaeological pottery fragments through use of a microwave-assisted silica gel and aminopropyl solvent protocol developed for the isolation and concentration of free fatty acids in marine sediments. Subsequent isotopic analysis of the surviving C16:0 and C18:0 saturated fatty acids revealed ∂13C ratios consistent with those of adipose fats of ruminant and non-ruminant animals pastured on lands adjacent to the Jordan Valley. The high recovery of diagnostic compounds from the al-Basatîn material is discussed in context of a wider examination of the initial development and use of pottery in the Fertile Crescent, and the emerging debate concerning the efficacy of stable carbon isotope values in characterizing organic residues embedded in pottery fragments recovered from the earliest ceramic horizons in the Middle East and Europe. 相似文献
